Page Six reports that MKO was spotted at the Neil Lane boutique in Los Angeles trying on engagement rings this past weekend. And it’s not her first time! She stopped by in mid-November, as well, and a few other times since. A source says Mary-Kate tried on rings priced at over $100,000, which isn’t super shocking considering she’s been a self-made millionaire since grade school.

Her beau, Olivier Sarkozy, is no slouch either. He’s a banker who currently serves as the Managing Director of the Carlyle Group in New York, presiding over billion-dollar deals. The two have been dating for around a year, and caused headlines for their age difference. She’s 27, and he’s 44.

Do you think Mary-Kate is on her way to being a married lady? What do you think of this coupling? What do you think an Olsen twin wedding would be like? Tell us in the comments below or tweet us @OKMagazine.
